Application filed February 11, 1921. Serial No. 444,254.

To all whom it may concern:

Be it known that 1, Cinemas H. KLEIN, residing at Jersey City, in thecounty oi": Hudson and State of New Jersey, have invented certainimprovements in Heaters for Soldering Coppers, of which the following isa specification.

This invention relates to improvements in torches or heaters for use inconnection with certain classes of heating fuel, and more particularlyfor use with containers of the mercantile article known as solidifiedalcohol.

In the use of torches tor the purpose of heating; soldering coppers orlike implements, accidents such as fires frequently-0ccur due to thealcohol. kerosene or other in flammable liquid contained in saidtorches, flooding out therefrom, or due to the upsetting of the torches.In other cases the varnish of cabinet work has been damaged by thesolvent action of the liquid by the accidental spilling thereof from thetorches. Further objections to said torches are that there isconsiderable waste attending the transfer of the liquid from itsoriginal container as well as the evaporation of said liquid. accordingy, it is'one of the objects of the present invention to provide a torchor heater which will overcome the disadvantages above mentioned, as wellas incorporate said burner with additional novel features, wherebyeconomy and efficiency may be effected as will hereinafter appear.

In, the accompanying drawing which illustrates one embodiment of theinvention, Figure 1 is a perspective view of the burner detached; Fig. 2is a perspective view oi? the fuel receptacle in which the solidifiedalcohol is contained; Fig. 3 is a perspective view of a stand adapted tohold the fuel receptacle; Fig. a is a perspective view of the coverwhich fits over the burner and engages the tapered sides of the standshown in Fig. 3, and Fig. 5 is an elevation of the assembled parts whichcomprise the heater.

The invention will be now more fully un-' derstood from the followingdetailed description.

In the drawing, the numeral 1 represents a burner-member which ispreferably of the configuration shown, it being hollow and having arounded top 2 and an annular side-wall 3. The side-Wall 3 terminates atthe bottom in an edge adapted to be seated on the upper rim-surface ofan open can or container of solidified alcohol, such as is indicated inFig. 2, it being understood that the usual top or closure member of thecan has first been removed. A central opening or burner-hole 4c ofsubstantially rectangular form is provided in the top 2 and in said topon the shorter sides of the burner-hole l are formed grooves 5, 5. Thesegrooves extend from the outer edge of the top 2, and terminate in prongs6, 6 which extend into the burner-hole and either of said grooves withits associated. prong provide aseat for a soldering copper. Two seriesof apertures 7 are provided in the side-wall 3 parallel withtthe longersides of the rectangular burner-hole 4, there being a space between theend of each series.

It is preferable that the central aperture of carh series be of thelargest area, and that each succeeding aperture on either side thereofshall be of a decreasing area, the terminating apertures being thesmallest of the series. The, apertures 7 serve as airinlets throughwhich a draft is produced so as to force the issuing flame from the fuelin the receptacle 18 in a central longitudinal direction against thesides of the soldering coppe'rs. Thus when an iron is seated in eithergroove and associated n'ong. the flame emitted through the burner-hole 4will encircle it.

The stand 8, shown in Fig; 3. is preferably made of material which is apoor heat conductor and which is non-inflammable, such as bakelitc orthe like. The stand is provided with a base-portion 9 having an upwardlytapered side-wall 10, about the bottom of which extends a peripheralflange 11. Support-s 12 are disposed in spaced relation about the edgeof the underside of the base-portion 9, while sup-ports 13 upon whichthe fuel receptacle 18 rests, are disposed about the upper-side of thebase 9 and inner portion of the side-wall 10 in such manner that theirvertical positions about the edge of said base will be different fromthe positions ofzsupports 12. Cut-awayportions 14: are provided on theinner surface of the wall 10 between the supports 13 to permit theentrance of air to the space beneath the fuel receptacle. Thearrangement of the supports12 and 13 and cut-away portions 14, in themanner indicated, allow a maximum air circulation beneath the fuelreceptacle l8 and base 9, and also beneath the stand and the surface onwhich it is supported, so that any .heat conveyed to said supportingsurface when the heater is in operation will be of negligible characterand no damage will result therefrom.

The cover 15 shown in Fig. 4 is preferably of the configurationindicated, and is adapted to fit over the burner-member andfuel-container. It has a tapered wall 16 adapted to register with thetapered sidewall 10 of the stand 8 and co-operate therewith in providingan air-tight enclosure whereby the fuel within the receptacle isprevented from disintegrating, due to the evaporation of the alcohol,thus making un necessary the removing and replacing of the usualfriction top cover of the fuel receptacle. The cover 15 when applied asoutlined above also functions to extinguish the flame issuing from theburning fuel. A beaded-edge 17which is provided at the bottom of- -thecover maintains the rigidity between the cover and stand.

From the foregoing, it is thought that the construction, operation andmany advantages of the herein described and delineated invention, willbe apparent to those skilled in the art, without further description,and it will be understood that various changes in the size, shape,proportion and minor details of. construction may be recomprising aburner-member for fuel receptacles having a flame-emitting opening ofsubstantially rectangular form, a groove in said burner-member at eitherend of said opening and a prong extending into said opening andco-operating with each groove for providing separate seats for saicoppers.

3LA device for heating soldering coppers comprising a burner-member forfuel receptacles having a flame-emitting opening of such contour thatthe issuing flame therefrom. will conform to the shape of said coppers,a groove in said burner-member at either end of said opening, meansco-ope-rating with each groove for providing separate seats for saidcoppers,'and air-inlets comprising a series of apertures ofvaryingdimensions disposed at either side of said opening.

The combination of a heater having a stand for fuel receptacles saidstand hav- 7 ing a tapered wall, a burner-member therefor, an opening insaid burner-member for 'g; roviding egress for the issuing flame of thefuel, and a cover for said heater for extinguishing said flame andco-operating with the tapered wall of said'stand to provide anair-tightenclosure for the fuel. 7

The combination of a heater for soldering coppers having a stand forfuelreceptacles, said stand having a tapered wall,

a burner member for said receptacles hav-' inoano ening of substantiallrectan 'ular form for providing egress for the flame issuing from thefuel, anda cover for'extinguishing said flame and adapted to registerwith the tapered wall of said stand to provide an air-tight enclosurefor the fuel and a unitary and portable structure for the L heater.

In testimony whereof I have 's'igned'my name to this specification this9th day of February 1921.

CHARLES H. KLEIN.
